GAE (Mirrorrr) Proxy - Youtube Issue.

[Gavin Youker]

I have a proxy server called http://gav-proxy.appspot.com/ 

For some reason, every time I go to to youtube and go to a video, the "youtube.com/" gets cut out of the URL. When I simply type it back in, the video plays. This only happens when I am on youtube already in my proxy, then go to a video. Please try it yourself and tell me why this occurs? Is there a way to fix this?

Thank You.
